Roofs with pitches of 10 to 20 are often called low pitched roofs and special considerations need to be made particularly on the overlap between tiles to avoid water being blown into the roof by the wind. The basic cold roof construction consists of rafters set at up to 600mm centres underlay laid horizontally over the rafters with a slight drape between each rafter and tile battens nailed directly through the underlay into the rafters.
